Talar Tilt

Background: Osteochondral lesion of the talus (OLT) is commonly found as a concomitant pathologic lesion in a large proportion of patients with chronic lateral ankle instability (CLAI). This study investigated which characteristics in a patient with CLAI increase the risk for OLT. Methods: Three hundred sixty-four patients who underwent a modified Broström operation for their CLAI were reviewed retrospectively. The characteristics of each patient and variables associated with OLTs were investigated. Statistical analyses were performed to determine the effect of each potential predictor on the incidence of OLT, and to evaluate the associations between the patient characteristics and variables associated with OLTs. Results: Patients with OLTs were more frequently female (female vs male: 63.1% vs 43.9%, P = .003). In addition, the lesion sizes were larger in female patients (female vs male: 113.9 ± 24.9 mm2 vs 100.7 ± 18.0 mm2, P = .002), and medial lesions were more common in female patients (female vs male; 93.3% vs 81.8%, P = .036). The lesion sizes were larger in patients with a wider talar tilt angle ( P < .001), and patients with a medial OLT showed a wider talar tilt angle (12.0 ± 2.0 degrees vs 10.3 ± 2.2 degrees, P = .002). Conclusion: In this CLAI patient cohort, we found female patients to be at greater risk for OLTs than male patients. Furthermore, CLAI female patients with concomitant OLT had on average a larger lesion size, more frequent OLT medial position, and were associated with wider talar tilt angles, suggesting that females had more intrinsic ankle instability than males. Level of Evidence: Level IV, retrospective case series.

Modified Broström Procedure

Category: Ankle, Arthroscopy Introduction/Purpose: The gold standard for the surgical treatment of chronic lateral ankle instability is the modified Brostrom procedure. Surgery aims to re-establish ankle stability and function, without compromising ankle motion. Recently introduced all inside arthroscopic modified Brostrom procedure coincide with the goal on that aspect. The purpose of this study was to investigate the early outcomes of all inside arthroscopic modified Brostrom operation for chronic ankle instability. Methods: From January 2015 to August 2016, 30 patients were included. The visual analog scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) ankle–hindfoot score, Foot and Ankle Outcome Score (FAOS), and Karlsson score were used to evaluate clinical outcomes. Anterior talar translation and talar tilt were used to evaluate radiologic outcomes. All patients had lateral ankle instability. All patients had giving way, persistent pain, and an inability to resume their preinjury activity level for more than 6 months. Clinical outcome evaluations were performed preoperatively, at 3 months and 6 months postoperatively, and at a final follow-up using the VAS score, the AOFAS ankle-hindfoot score, FAOS, and Karlsson score. Radiologic outcome evaluations were performed preoperatively and at 1 year postoperatively at final follow-up using anterior talar translation, and talar tilt angle. Results: Thirty patients (19 males and 11 females) were followed up for a mean of 11.0 (range 4 – 23) months. The VAS, AOFAS, 1 FAOS subscale (Quality-of-life) and the Karlsson scores were improved significantly at the each follow-up period of 3 month, 6 month and 1 year postoperatively. Other 4 subscales of FAOS showed no significant outcomes (Table 1). The mean anterior talar translation and talar tilt showed significant improvements from 5.8 mm (SD = 0.4) and 7.9° (SD = 1.0) to 5.3 mm (SD = 0.3) and 5.7° (SD = 0.6) at the final follow-up each (p = 0.034, p=0.034). Conclusion: The arthroscopic modified Brostrom technique could be a viable alternative to the gold-standard open modified Brostrom procedure for anatomic repair of chronic lateral ankle instability. It can yield outstanding functional and clinical outcomes without adverse effects in terms of pain.

Category: Ankle Arthritis Introduction/Purpose: In recent years, total ankle arthroplasty (TAA) has been widely performed for severe ankle osteoarthritis (OA). However, TAA is not always successful in cases of advanced varus; in fact, some researchers have stated caution regarding its indication. Previously, to elucidate the pathological condition of ankle OA using MRI, we investigated that confirmed the existence of an association among the Takakura–Tanaka classification, foot and ankle alignment, and bone marrow edema (BME). In this study, we focused on the talar tilt angle and compared the cases of terminal ankle OA as per Takakura– Tanaka classification (stage 3b and 4) wherein this angle exceeded 15° with those wherein it did not exceed in terms of the mode of BME onset. Methods: Of 616 cases of ankle OA diagnosed in our hospital between May 2009 and January 2018, we examined the MRI images of 52 feet of 50 patients diagnosed with severe ankle OA. The talar tilt angle with the ankle under load was measured using frontal X-ray, following which the presence/absence of BME was determined by dividing the talus, subtalar, and Chopart’s joints into 22 regions (areas 1–11 and 1’–11’). In statistical analysis, we first obtained the total number of BME incidences for each case. Then, after dividing this disease group into severe varus (SV; talar tilt angle = 15° or more) and mild varus (MV; talar tilt angle < 15°) groups, we compared t-test scores for the respective BME incidence rates. Furthermore, we used Fisher’s exact test to examine differences in terms of BME incidence rates between the two groups for each subdivided region. Results: No significant differences were found between the two groups in terms of BME incidence rates for each case. However, the rates in each area were significantly lower in the SV group than in the MV group for area 2 (SV group, 14%; MV group, 57%) and area 4 (SV group, 7%; MV group, 39%), i.e. the SV groups corresponding to the outer surface of the trochlea talar. Conversely, in the subtalar joint, the rates were significantly higher in the SV group than in the MV group for area 10 (SV group, 36%; MV group, 11%) and area 10’ (SV group, 29%; MV group, 5%), i.e. the medial surface of the calcaneus. Conclusion: In cases of severe ankle OA wherein the talar tilt angle exceeds 15°, the load exerted on the outer side of the talus decreases in the talar joint, whereas a greater load is exerted on the medial subtalar joint located at the innermost side in the subtalar joint. Differences in terms of the mode of BME incidence in the subtalar joint, which is not replaced with normal TAA, may be a poor prognostic factor for postoperative TAA.

Category: Sports; Ankle Introduction/Purpose: Destabilizing injuries to the lateral ligament have relied on physical examination and radiographic stress test for diagnosis, with a focus on anterior translation and tilting of the talus relative to the tibial bone. Portable ultrasonography (PUS) has increasingly been used in the clinical setting, allowing dynamic and non-invasive evaluation. The primary aim of this study was to assess the anterior translation and tilting of the talus with PUS in various stages of lateral ankle ligamentous injury. Secondary, we compared the instability values measured with PUS with those measured on fluoroscopy. Third, we aimed to determine the optimal cutoff values of the PUS that distinguish stable from unstable state. Methods: 8 fresh-frozen cadaveric specimens underwent PUS and fluoroscopic evaluation for lateral ankle stability. The assessment was done with all ligaments intact and later with sequential transection of the anterior-talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the posterior-talofibular ligament (PTFL). In all scenarios, 2 loading conditions were considered; 1) Performing the anterior drawer test under 50N and 80N of force, anterior translation was measured with PUS and fluoroscopy; 2) Performing the talar tilt test under 1.7Nm of torque, the lateral clear space (the distance between the fibular tip and lateral process of the talus) was measured with PUS, and the talar tilt angle was measured with fluoroscopy (Figure1). Pearson’s and Spearman’s rank correlation was used to determine the correlation. Youden’s J statistic was used to determine the optimal cutoff values for the PUS to distinguish intact or ATFL injury versus ATFL-CFL or ATFL-CFL-PTFL injuries under various loading conditions. Results: Strong positive correlations were found between PUS and fluoroscopic measurements (Pearson correlation:r=0.78- 0.85). PUS and fluoroscopic measurements during anterior translation and talar tilt test increased as additional ligaments were transected (Spearman’s rank correlation: anterior translation; r=0.74, p < 0.001: talar tilt; r=0.81, p<0.001). Inter-rater and intra- rater reliability for PUS and fluoroscopic measurements were all excellent (ICCs >=0.8). The optimal PUS cutoff values for distinguishing intact or ATFL injury from ATFL-CFL or ATFL-CFL-PTFL injuries were >=3.40mm (sensitivity 87.5%, specificity 81.25%) and >=4.78mm (sensitivity 87.5%, specificity 81.25%) of anterior talar translation under 50N and 80N of force respectively, as well as >=3.09mm (sensitivity 75%, specificity 93.75%) of the lateral clear space under 1.7Nm of torque. Conclusion: Portable ultrasonography for the diagnosis of lateral ankle instability was strongly correlated with fluoroscopic findings, and thus, can be a valuable diagnostic tool at the point of care. We recommend future in vivo research to investigate the accuracy of this new ultrasound application in a clinical setting.

Talar Tilt

We have performed an ongoing retrospective and prospective multi-institutional review of 50 patients who underwent 53 lateral ligamentous reconstructive procedures of the ankle. The point grading system used for postoperative evaluation of our patients allowed for classification of functional activity. The grading system included evaluation of the patient's return to preinjury activities and athletics, degree of pain, degree of swelling, number of recurrent sprains, and any disability that the patient incurred secondary to the tendon transfer. Preoperative and postoperative stress radiographs were obtained to evaluate the talar tilt angle. Of our 53 lateral ankle ligamentous reconstructions, we consider 45 to be excellent, with the patients returning to full activity and athletics. Our results show no statistically significant difference in long-term function among the five ligamentous repairs employed in this series (Pearson Chi-square test; χ2 = 2.30, df = 4, P = 0.68). No correlation could be made between the long-term clinical response of the various procedures and the postoperative talar tilt angle. We conclude that lateral ligamentous reconstructive repairs of the ankle are indicated, and that good or excellent clinical results, greater than 91 %, can be obtained with any of the five reconstructive procedures, performed correctly.
